Floats are workable between temperatures -30°C and +65°C and offer good resistance against oil and chemicals. Each float has brass eyelets and available in either 1.06mtrs or 2.06mtrs lengths. The width will depend upon the rope size. Floating Pick-up/Messenger Rope Manufactured from high tenacity co-polymer yarns and available in 3, 4 or 8 strand, floating pick-up/ messenger rope is flexible and easy to handle and provides excellent abrasion resistance and strength. Providing permanent floatation in water, the system is fully UV stabilised and the wet strength is equal to dry strength. Chafe Chains Chafe chains can be supplied configured to a customer’s own specification, our range of chafe chains include: • Chafe Chain A OCIMF 1993: For use with full range of ship sizes • Chafe Chain B OCIMF 1993: For use with ships of 350,000 tonnes or less deadweight • Chafe Chain C OCIMF 1993: For use only in combination with chafe chain A or B at terminals accepting ships fitted with 54mm chain stoppers • Chafe Chains as per OCIMF 2007, 4th Edition: Recommendations for equipment employed in the Bow mooring of conventional tankers at single point moorings’. Inherent Buoyancy Flotation System Hawsers that incorporate our integral floatation systems are supplied with an additional layer of closed cell buoyancy foam ensuring that sufficient buoyancy is calculated to support the hawser in seawater. This is secured using an additional outer protective layer which can also be covered in a tough resilient polyurethane elastomer coating. The system works to enhance the mooring hawser’s abrasion resistance to external items in the field and has the added benefit of reducing the amount the rope will flex with the wave action. Tubular Rope Float Survitec Group tubular rope floats are manufactured from closed cell polyethylene foam, encapsulated within a tough polyurethane elastomer skin. This high performance outer skin is resistant to ultraviolet degradation and provides protection from abrasion. Tubular rope floats can be supplied factory fitted, or ‘split’ for retro-fitting to existing hawser operations by banding or strapping. Offshore Mooring Systems – Hawser Shackle Offshore Mooring Systems – Residual Hawser Strength Testing Offshore Mooring Systems – Marine Hose Ancillary Equipment Hawser Shackle • Material: forged high alloy steel • Finish: galvanised or painted • Minimum break load 5 x SWL Survitec Group can help operators to understand the hawser behaviour and performance in specific field operations by residual strength testing of used and retired mooring hawsers. Our high tech laboratory has the capability to analyse mooring hawsers for condition, signs of internal abrasion damage or ingress of foreign particles, we also perform residual break tests. This information helps operators understand the hawsers in use at their terminal allowing informed judgements to be made on current and future retirement programmes. Survitec Group is able to source and supply marine hose ancillary equipment meeting OCIMF standards. Products include: • Butterfly valves, camlock couplings, blind flanges • Pick-up and snubbing chains, marker buoys • Studbolts, nuts and gaskets • Hinged hose floats for submarine hoseline systems • Spool pieces, reducers, y-pieces OCIMF – Special Valves 1 Chemical Hoses
